  • Patent number: 7190568
    Abstract: A multilayer contact approach for use in a planar solid oxide fuel cell stack includes at least 3 layers of an electrically conductive perovskite which has a coefficient of thermal expansion closely matching the fuel cell material. The perovskite material may comprise La1-xEx Co0.6Ni0.4O3 where E is a alkaline earth metal and x is greater than or equal to zero. The middle layer is a stress relief layer which may fracture during thermal cycling to relieve stress, but remains conductive and prevents mechanical damage of more critical interfaces.

  • Publication number: 20060110647
    Abstract: A solid oxide fuel cell stack may include repeating fuel cell units each having a planar fuel cell, an interconnect, a cathode contact layer disposed between sealing strips, and an anode contact layer disposed between sealing strips. The sealing strips have end extensions which overlap with corner extensions on the interconnect. The extensions stack to form vertical columns which enclose the external manifolds, along with a manifold plate.

  • Publication number: 20040197636
    Abstract: A solid oxide fuel cell stack includes a fuel cell unit consisting of a fuel cell framed by a cell holder plate and upper and lower cushioning elements. The fuel cell unit is stacked with flow field seals and solid flow separator plates. The fuel cell thus floats without direct contact with rigid stack elements.

  • Publication number: 20040135324
    Abstract: A flexible seal for use in a solid oxide fuel cell stack is formed from a fibre matrix with a plurality of solid particles through tape casting method. The fibres and particles are preferably ceramic and may be formed from alumina or zirconia. The seal may be formed by forming a slurry of fibres, particles, a binder and a non-aqueous solvent, tape casting the slurry, drying the tape seal, die-cutting, prior to installation in the fuel cell stack.

  • Patent number: 6611826
    Abstract: A binary learning system characterized by consisting of an input layer having binary input terminals, a coupling layer, a first binary gate layer with first similar logical elements, a second binary gate layer with second similar logical elements, and an output layer, so as to form a learning network, in that each coupling condition between the adjacent layers limited to one way directing from their inlet side to the outlet side, and each layer has independent routes without mutual coupling conditions, the coupling layer having means for selecting either one of a direct coupling condition and a coupling condition routed through an inverter, relative to routes from the respective signal units in the input layer to the respective signal units in the first binary gate layer, in such manner that the selected coupling condition is adapted to eliminate or decrease the respective errors between original output signals at the output layer and monitor signals in the learning network.
